Director of Business Development

Our Director of Business Development, Hovick Suleymanian, has been with ONE Family since 2013. Though a proven top-producing real estate agent during his first 2 years with the company, in 2015, Hovick has agreed to up the ante by leaving his full time, high-level position at a Fortune 500 company so as to expand his role at ONE Street. With a wealth of technical knowledge, years of experience in corporate America and a successful track record as an entrepreneur, Hovick is well positioned to advise and consult ONE’s leadership and, more importantly, spearhead the development and improvement of ONE’s business and business relationships as it expands its reach to national markets.

Hovick brings to ONE Street over 15 years of business analysis and project management experience in the Information Technology and Finance sectors, including 11 years serving as the Lead Business Systems Analyst at SunTrust Bank, Inc. where, among many things, he consulted SunTrust executives on the technical and business aspects of a host of initiatives. Hovick has earned so many expert designations in system development, management, database and data analysis, programming, web design, e-commerce, and multimedia development that there are too many to list here. However, those designations lend toward his multi-faceted approach to technology, , management, business development and training.

Hovick holds two Bachelors Degrees -- one in Physics from Yerevan State University and one in Biology from Virginia Commonwealth University. He also has a Masters Degree in Business Management and Information Systems from Virginia Commonwealth University.

In addition to his duties on the management team, Hovick is a full time Realtor, licensed in DC, MD and VA and is running a highly successful sales team of 8 agents which have produced over $100mln in sales 2 years. Hovick currently resides in North Bethesda MD with his wife and business partner, Lina and two lovely children.

Client Testimonials

Working With ONE Street Was A Pleasure

Working with ONE Street was a pleasure! We worked directly with Sam; while he oversees many agents, he always had ample time to devote to our house-hunt and patiently answer all our questions (at any time of day or night) which we had many of given that we were first-time homebuyers – and this is where Sam’s considerable expertise proved very helpful through-out the process. He had a wealth of knowledge he drew on to explain the dynamics of the DC real estate market to us and specifically how they applied to our search.

You Will NOT Be Disappointed

I’ve been doing business with Sam for many years. He’s helped me [sell] 3 of my houses and bought another one. I’ve had nothing but great experience with the way [he] handles the business from start to finish! Buying / selling a house is definitely one of most stressful but also very exciting momentsof your life. But when you have an awesome agent like Sam, it makes the whole [transaction] smoother and a lot less stressful. Don’t waste your time and hire Sam to partner with you and you will NOT be disappointed!!!
